Swap variable without temporary variable
meanwhile C:
a=a+b
b=a-b
a=a-b

while python:
a,b=b,a

Python be like:B*tch Please

Parallel assignment is like the single good thing about Python

I can probably count on one hand the number of times I have wanted to swop two variables in a real life application.

@FrodoSwaggins Well, yeah I just mean the syntax. Fuck Python

Python do it because is high level language ... End

@jak645 They do it because it's cool. That's the only cool thing

yeah, when you do that in python, it is actually doing this under the hood, essentially:

# a, b = 1, 2
_ = (1, 2)
a = _[0]
b = _[1]

you just dont usually care because Python is slowish anyway in comparison to some other languages, but you could find a performance hit by doing this in certain situations. It is implementation specific though

@nekokatt additionally, on ARM and x86, you tend to use xor rather than +- to swap:

int a = 132;
int b = 67;

a ^= b ^= a ^= b;

C:
a ^= b;
b ^= a;
a ^= b;

^ is bitwise XOR

Don't ask me why it works.
